Implementation of IoT for Drinking Water Quality Monitoring

The need for user involvement in maintaining drinking water quality and other aspects like hygiene, environment sanitation, storage, diseases and disposal are critical elements to maintain and improve the quality of drinking water resources. It is also expected that by around 2020, India will be a ‘water stressed' state with per capita availability declining to 1600 cu m/person/year. At present scenario due to sewage discharge, discharge from industries, run-off from agricultural fields and urban run-of, over population and scarcity of drinking water is primary concern for this thesis. In addition, uncertain quantity of certain parameters in drinking water like; PH, TDS, turbidity, temperature, as well as due to conventional method of testing, quality may not be tested on real time basis. Advancement in Internet of things (IoT), sensors, wireless communications, microcontrollers (Arduino), mobile application(android), internet availability leads to focus this thesis on testing, monitoring, record keeping, alarming and suitable action can be suggested in improvement of drinking water quality. At the end this system would be simple, user friendly, flexible, low cost, highly efficient, reliable, robust and easily available at user end.
